Description
Leader’s horizontal Lift Check Valve (Bolted Cover) is supplied in 15 mm to 50 mm at Class 800. Check valves stop reverse flow without any external operation — line pressure alone opens and closes them. On a pump discharge they prevent backspin and the water hammer that follows an abrupt stop. Forged A105 gives a dense, void-free body — why forged construction is specified for small-bore high-pressure duty. Socket-welded ends suit small-bore high-pressure lines where a threaded joint would be a weak point. Normally fitted on pump discharges and at the point a branch joins a common header. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
